Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a skin grafting packing suturing device used in surgical operations. Background Art

[0002] Skin transplantation plays an extremely important role in the treatment of plastic surgery and burn surgery. Skin transplantation is very technical. Skin transplantation is to take out healthy skin cells from the healthy part of the skin for cultivation. After the culture is mature, they are extracted and sterilized, and finally implanted into the skin of the injured part. Before implanting the skin of the injured part, the epidermis of the skin needs to be slightly destroyed by laser to allow the new cells to reproduce. The existing skin grafting technology basically uses mechanical suturing tools to fix, bandage and brake the fresh skin graft. For fixation, bandage and braking, the existing method is to use needle and thread mechanical suturing tools to sew the recipient area of ​​the fresh skin graft repeatedly and uninterruptedly, and fix it with long-line packaging. There are many problems in this method. For example, the needle and thread mechanical suturing tools cause re-trauma and damage to the fresh skin graft and the recipient area tissue. For example, the needle and thread mechanical suturing tools repeatedly thread and knot fix the operation, which is highly professional, difficult and time-consuming, and not easy to popularize and promote. In addition, long-term uninterrupted suturing produces a large amount of blood, is easy to get infected, and has low skin viability. Summary of the invention
